Specification of Letters Patent.

Patented Oct. 29, 1907.

Application filed November 17. 1906. Serial No. 343.841.

To all whom it may concern:

Be it known that 1, JOAQUIN 'Fnnnnnns, a subject of the King of Spain, and a resident of l'labana, Cuba, have invented a new and Improved Calendar, of which the following is a full, clear, and exact description.

This invention relates to certain improvements in calendars, and more particularly to calendars in which the same numerals and designations of the days of the week may be employed for each month in the year by adjusting their relative positions, and also may be used for any number of years, thus rendering the calendar good for an indefinite period.

More particularly, the invention relates to calendars in which a rotating dial is secured to a suitable support, and the -designations of the days of the months and the days of the week are so located upon the dial and its support, that any day of the week may be brought adjacent any desired day of the month.

The invention consists in certain features of construction and combination of parts, all of which will be fully set forth hereinafter and particularly pointed out in the claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures, in which Figure 1 is a front elevation of my improved calendar; Fig. 2 is a plan view of the rotating dial thereof; Fig. 3 is a longitudinal section, said section being taken on the line 33 of Fig. 4; and Fig. i is an elevation of the rear or back side of the device.

In the specific embodiment of my invention which I have illustrated in the drawings, there is provided a suitable support 10 of any suitable material, and, if desired, having any suitable advertising matter or pictures printed thereon. Secured to the support is a disk 11 cut substantially in the form of a circle, and having numerals representing the days of the month printed around the circumference thereof. These numerals preferably do not extend entirely around, but begin and end at points a considerable distance from the top. From the point 12 adjacent the numeral l, there is a slit or cut 13 extending across the disk to a point 1 f adjacent the numeral 31. This slit or cut preferably extends downward toward the center of the disk, but may be of any desired shape or configuration. Within the flap or tongue 15, formed by they cut 13 intermediate the points 12 and 14, there is provided substantially rectangular slot 16 extending radially in respect to the center of the disk. "he entire disk ill, save the flap or tongue 15, is secured to the support 10 in any suitable manner, but the lower edge, as well as the body portion, of the flap or tongue 15 is entirely free from the sup port, whereby the dial may rotate beneath the same.

Pivotally secured to the disk and support adjacent the center of the former is a dial 17 having the circumference thereof sub-divided into some multiple of seven, and letters or abbreviations representing the successive days of the week printed upon the dial adjacent the pcriphery thereof and within these sub-divisions. This dial is substantially circular in form and its diameter is slighfly less than the inner diameter of the annular row of numerals en the disk. The subdivisions around the periphery of the dial correspond with the printed numerals upon the disk, so that when the sub-divisions of any particular day of the week is brought adjacent a given numeral representing a day of the month, the remaining sub-divisions having marked therein the successive days of the week will register with the successive numerals. As illustrated in the drawings, when the dial is so placed that the first day of the month registers with Monday on the dial, then the second day of the month will register with 'lucsday, and the remaining days of the month will register with their corresponding days of the week. Thus it is only necessary to adjust the position of the dial once every month, and in order that the particular day may be clearly indicated by a glance at the calendar, 1 provide a hand or pointer 18 pivoted at the center of the dial and the disk. This hand or pointer may be readily moved each morning to the particular day, so that said day is clearly indicated.

The entire upper portion of the dial lies beneath the 1 projection or flap 1?) of the disk, and the portion of the dial normally concealed by said projection is provided with the names of the months in the year so arranged that when the name of any particular month is exposed fhrough the slot .11 of the projection, the day of the week upon which said month sfarfs will be opposite the numeral il. representing the first day of the month. The arrangement of the months of the year is clearly shown in Fig. .2, from which figure it will be seen that the names are arranged in radial lines from the center, and those months which begin upon the same day of the week are arranged in the same radial line. As all of the names of the months, save those in one particular radial line, will be concealed beneath the flap or projection 15, and as it is necessary to bring toviewthroughsaidslotthenameofthedesircd month, the rotation of the dial will bring the name of the correct day of the week opposite the numeral representing the first day of the month. As nearly all of the other names of the months will be concealed, it is evident that the calendar exposes to view the name of the month, as well as indicating the .days of the week upon which each successive day of the month falls during that month. As the first day of any particular month falls upon a different day of the week in each succ sive year, the arrangement of the days of the month above referred to will only be good for the particular year for which the calendar is prepared and for certain other years at various lengths of time therefrom.

months of the year, the names being arranged in radial lines butpreferably in the reverse order radially out ward to that utilized in the arrangement of the names of the months upon the upper portion of the dial. Printed upon the disk and upon a space substantially equal in shape and area to that of the slot 19 are numerals representing the successive years throughout any given period. These numerals are arranged successively in lines lying in the circumferences of circles and seven numerals are printed in each line. As each leap year occurs the numeral of this year is printed in two successive spaces due to the greater length of said year. As many numerals are used and as many years covered by the calendar as may be desired, the limit being determined only by the mnnber of rows of the numerals and the radial distance across the slot 19. In order to determine the day of the week upon which any given day of the month in any year will occur, it is only necessary to move the dial until the name of the desired m'onth registers with the numeral of the desired year, and then the calendar for that month in that particular year will be shown by the registry of the names of the days of the week with the numerals representing the days of the month. If, for instance, it is desired to know the day of the week upon which the 23rd day of January, 1917, will occur, the dial would be moved to the position shown in Fig. 1, in which January is in the same radial line as is the year 1917, and it will be noted that the 23rd day falls on Tuesday, as indicated by the pointer.

The names of the month printed at the upper portion of the dial would be good only for one particular year or other years at various distances therefrom, but as a calendar is seldom employed more than a single year and becomes soiled and is replaced by a new one at the end df that time, the names of the months at the upper portion of the dial are employed during the year for which the calendar is prepared and the name of the particular month is exposed through the slot 16; but in case it is desired to produce the calendar of any desired month in any other year than the year for which the calendar is prepared, the names of the months printed adjacent the slot 19 will be brought into registry with the numerals on the disk beneath said slot and the de sired month thus obtained.

In order to prevent the too free rotation of the dial 17, due to accidental jarring or dropping, I preferably provide a slot 21 in the support at a point somewhat above the pivot of the dial and pointer, and this slot is sutficiently long to receive the upper edge of the dial 17, as indicated in the view of the reverse side of the calendar shown in Fig. 4. The upper edge of the dial is forced backward through this slot and engages with the support at both sides thereof. Too free rotation of the dial is thus prevented and all liability of the dial being accidentally rotated due to its greater weight on the side opposite to the slot 19 or due to any other accidental cause, will be effectively prevented. The support is provided with an opening 22 or any other suitable means, whereby it may be suspended, and the face of the support 10, as previously stated, may be utilized for advertising purposes or decorated with any suitable picture or design.

Various changes may be made within the scope of the appended claims but without departing from the spirit of my invention.

Having thus described my invention, I claim as new and desire tosecure by Letters Patent:

1, A calendar, comprising a suitable support, a statio11- nrymember secured thereto, a rotary member pivoted to said stationary member and said support, and a projection or flap adapted to conceal from view a portion of the rotary member and having an opening therein, said support being provided with an opening beneath said projection 01' flap. through which extends a portion of the rotary member, whereby too free rotation of the latter is prevented.

2. A calendar, comprising a stationary member and a rotary member, said members being provided with the names of the days of the week and the numerals of the days of the month adjacent the periphery of the rotary member, whereby they may be brought into registry by the rotation of said member. said stationary member being provided with a slit connecting two points adjacent the periphery of the rotary member, and one edge of said rotary member eX tending through said slit and normally concealed by a portion of the stationary member, said concealed portion of the rotary member bearing the names of the months of the year. the concealing portion of the stationary member being provided with an aperture whereby said last mentioned names may be disclosed.

s. A calendar, comprising two members mounted to have a movement relative to each other, one of said members bearing the numerals of the days of the month and the other of said members bearing the names of the days of the week, said names and numerals being so placed as to be brought into registry by the movement of one of the members. one of said members being provided with a slit forming a [lap or projection integral with said member and Inning an opening within said flap or projection, and the other 01 said members having a portion thereof extend ing through said slit and lying beneath said flap and hearing the names of the months of the year, whereby the lattcr may be disclosed through said opening by the relative movement of the members.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
